Description

Technical Field

[0001] The present invention relates to the technical field of bending machines, and particularly relates to a stamping device for aluminum plate processing. Background Art

[0002] A bending machine is a mechanical device specifically used for processing metal plates. Its main function is to bend metal plates into specific shapes and angles. This device plays a crucial role in the manufacturing industry, especially in industries such as automotive, aerospace, construction, and household appliances. By applying appropriate pressure, the metal plate undergoes plastic deformation under the action of a mold, thereby achieving an accurate bending effect. The core components of a bending machine include an upper die, a lower die, a hydraulic system, and a control system. The precise cooperation of the upper die and the lower die determines the bending angle and shape, while the hydraulic system provides the necessary pressure for this process. For numerical control bending machines, they are also equipped with advanced programming systems. Operators can precisely control the bending process by inputting specific parameters, thereby ensuring the consistency and high precision of the dimensions and shapes of each product.

[0003] A Chinese patent document with the publication number CN118699137B discloses a plate bending machine for plate processing, which includes a frame and symmetric bending hydraulic cylinders fixedly connected to the front side of the frame. The telescopic ends of the symmetric bending hydraulic cylinders are fixedly connected with an upper die holder. The front side of the frame is also fixedly connected with a lower die holder. A support seat is hinged on the front side of the lower die holder. When bending a plate, the worker first places the plate on the support seat. After aligning the area of the plate to be bent with the upper die holder and the lower die holder, the bending hydraulic cylinders are started to drive the upper die holder to move downward to bend the plate. During the bending process of the plate, the support seat flips upward to support the plate.

[0004] In the above technology, when the worker performs the plate bending operation, since the plate itself occupies a relatively large space, it requires the worker to first carry the plate from a specific area for placing the plate beside the bending machine to the support seat. Subsequently, the worker starts the plate bending work. After completion of bending, the worker also needs to remove the bent workpiece from the support seat and place it in other designated areas. This process needs to be continuously repeated by the worker, that is, continuously carrying the plate from the placement area to the support seat, and after completion of bending, removing the workpiece and placing it elsewhere. Due to the heavy weight of the plate, this continuous carrying work consumes a considerable amount of physical strength of the worker. In addition, this operation method also reduces the overall efficiency of plate processing. Summary of the Invention

[0005] The present invention provides a stamping device for aluminum plate processing, aiming to solve the technical problems in the related technology that due to the heavy weight of the plate, it consumes a large amount of physical strength of the worker and results in low efficiency of plate processing.

[0006] A stamping device for aluminum plate processing, including a bending machine body, further comprising: A support frame installed on the front side of the bending machine body; A material storage mechanism, the material storage mechanism includes a lifting platform arranged on the right side of the support frame for carrying sheet materials. Limiting plates inclined to the left are respectively arranged on the left and right sides of the lifting platform. A retaining platform extending upward is arranged at the top of the limiting plate. The sheet materials are horizontally placed on the lifting platform, and the left and right ends of the sheet materials are respectively abutted against the limiting plates on their left and right sides; A feeding mechanism, the feeding mechanism includes a feeding plate rotatably installed on the right side of the support frame, a pulling rod slidably installed on the support frame in the left - right direction, and a second driving source for driving the pulling rod to move. When the feeding plate rotates, the right end of the feeding plate pushes the left end of the uppermost sheet material upward to deflect. After the sheet material deflects, the pulling rod moves to the right and enters below the sheet material. When the right end of the pulling rod moves to the right end of the sheet material, the left end of the sheet material deflects downward under the action of gravity and rests on the pulling rod. Then the pulling rod drives the sheet material to move to the left. After the pulling rod resets, the lifting platform rises by the height of one sheet material.

[0007] The effect is that: by setting the material storage mechanism, before bending the sheet materials, multiple sheet materials can be placed on the discharging mechanism first, and by setting the feeding mechanism, the sheet materials in the material storage mechanism are transported to the support frame. After a worker finishes processing one sheet material, there is no need to carry the sheet material from elsewhere to the support table. At the same time, by setting two inclined limiting plates, when initially placing multiple sheet materials, the left end of the upper - side sheet material will extend beyond the left end of the lower - side sheet material. Therefore, by rotating the set feeding plate, the uppermost sheet material can be lifted from the left end of the sheet materials. Then, by setting the pulling rod that moves to the right, after the pulling rod moves to the right end of the sheet material, the left end of the sheet material will move downward under the action of gravity and thus rest on the pulling plate. When the pulling plate moves to the left, since the sheet material does not contact the sheet material below it, it can avoid the friction between sheet materials during feeding, thereby preventing the surface of the sheet material from being scratched.

[0008] Preferably, a gear is fixedly installed on the feeding plate, and a rack meshing with the gear is arranged on the pulling rod.

[0009] Preferably, an elastic member I is installed between the feeding plate and the support frame, and the elastic member I is used to make the right end of the feeding plate located to the left of the uppermost sheet material.

[0010] The effect is that: by setting the elastic member I, it can be ensured that after the pulling rod resets, the right end of the feeding plate is located to the left of the uppermost sheet material, enabling the feeding plate to lift the sheet material again next time.

[0011] Preferably, the second driving source includes a lead screw five rotatably installed on the support frame and arranged in the left-right direction, and a second motor whose output end is connected to the lead screw five. The material pulling rod is in threaded cooperation with the lead screw five.

[0012] Preferably, a roller is rotatably installed at the right end of the material pulling rod. A one-way bearing is arranged between the roller and the material pulling rod. When the material pulling rod moves to the right, the roller abuts against the sheet material, and at this time, the inner ring and the outer ring of the one-way bearing rotate relative to each other.

[0013] The effect is that by arranging a roller at the right end of the material pulling rod, after the sheet material is lifted, the roller contacts the sheet material, enabling the roller to move along the sheet material, avoiding damage to the sheet material caused by sliding friction. By arranging a one-way bearing, the roller can only rotate clockwise, preventing the sheet material from slipping off the material pulling rod when the material pulling rod resets.

[0014] Preferably, the support frame includes a first side plate fixedly installed on the bending machine body, a second side plate slidably installed on the first side plate in the front-rear direction, and a second driving member for driving the second side plate to move. There are two material pulling rods, which are respectively slidably installed on the first side plate and the second side plate in the left-right direction.

[0015] The effect is that by arranging the first side plate and the second side plate, and slidably installing the second side plate on the first side plate in the front-rear direction, when bending operations need to be performed on sheet materials of different sizes, the distance between the first side plate and the second side plate can be adjusted to provide support for various sheet materials of different sizes.

[0016] Preferably, a plurality of rotating rods abutting against the sheet material are arranged in an array along the left-right direction on the upper end surfaces of the first side plate and the second side plate.

[0017] The effect is that a plurality of rotating rods are installed on the upper end surfaces of the first side plate and the second side plate. The function of these rotating rods is to convert the original sliding friction between the sheet material and the first side plate and between the sheet material and the second side plate into rolling friction, which can reduce the resistance when the worker moves the sheet material. In addition, it also reduces the possibility of the sheet material surface being scratched due to friction, thereby protecting the surface quality of the sheet material.

[0018] Preferably, a first comb-shaped plate and a second comb-shaped plate are slidably installed on the lifting platform in the left-right direction. An elastic member two is arranged between the first comb-shaped plate and the lifting platform to make the first comb-shaped plate move to the left and abut against the limiting plate. An elastic member three is arranged between the second comb-shaped plate and the lifting platform to make the second comb-shaped plate move to the right and abut against the limiting plate.

[0019] The effect is that by arranging the comb-shaped plates, during the rising process of the sheet material, it can be ensured that the lifting platform can always effectively provide continuous support for the lower end of the sheet material.

[0020] Preferably, a base is installed below the lifting platform, and two limiting plates are slidably installed on the base in the front-back direction.

[0021] The effect is that by slidably installing the two limiting plates on the base in the front-back direction, when processing plates of different sizes, the positions where the two limiting plates are in contact with the plate can be adjusted, so that the limiting plates are preferably in contact with the middle position of the plate, avoiding the situation of the plate falling during subsequent processing.

[0022] Preferably, sliders are slidably installed on the upper end surface of the base in the left-right direction. The sliders are located on the right side of the lifting platform, and the two limiting plates are respectively slidably installed on the base and the sliders in the front-back direction. The effect is that The effect is that by setting the sliders, the distance between the two limiting plates can be adjusted, and thus plates of different sizes can be adapted.

[0023] Adopting the above technical solution, the beneficial effect of the present invention is: By setting the material storage mechanism and the feeding mechanism, multiple sheets of plates can be neatly placed beside the support frame at one time. This process is assisted by the limiting plates to ensure that the multiple sheets of plates are arranged in a staggered manner in the up-down direction, so that the left end part of the upper layer of the plate can appropriately extend beyond the left end of the lower layer of the plate. Subsequently, through the precise cooperation between the feeding mechanism and the material storage mechanism, these plates can be automatically conveyed onto the support frame. This automated process significantly reduces the number of times workers repeatedly pick up and transport plates on the production line, thus not only improving the efficiency of plate bending processing but also effectively reducing the physical labor intensity of workers.

Detailed Description of the Invention

[0038] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0039] As Figure 1As shown, a stamping device for aluminum plate processing in an embodiment of the present invention includes a bending machine body 1, a support frame 2, a storage mechanism 3, a feeding mechanism 4 and a conveyor (not shown in the figure). The support frame 2 is installed on the front side of the bending machine body 1, and is used to support the sheet material 5 to be bent. The storage mechanism 3 is arranged on the right side of the support frame 2, and is used to store a plurality of sheets 5 to be bent. The feeding mechanism 4 is arranged on the support frame 2, and is used to convey the uppermost sheet material 5 to be bent in the storage mechanism 3 to the support frame 2. The conveyor is arranged on the left side of the support frame 2, and is used to convey the bent workpiece outward for the next processing step.

[0040] During the bending process of the sheet material 5, when a sheet material 5 has been bent and completed, the worker will first place the bent workpiece on the conveyor, and then the loading mechanism 4 will start to operate. It will lift the top sheet material 5 from the storage mechanism 3 and accurately deliver it to the support frame 2. After this link is completed, the worker will continue to use the bending machine body 1 to further bend the sheet material 5. When this bending process is successfully completed, the worker will repeat the above steps again until all the sheets 5 in the storage mechanism 3 have been processed. In order to further improve work efficiency and reduce the labor intensity of workers, workers will place multiple sheets 5 in the storage mechanism 3 at one time, which can significantly reduce the number of times the material is taken, thereby effectively improving the overall efficiency of the bending process of the sheet material 5.

[0041] like Figure 1 , Figure 2 As shown, the bending machine body 1 includes a frame 11, an upper die frame 12 and a lower die frame 13. The lower die frame 13 is fixedly mounted on the frame 11, and the upper die frame 12 is slidably mounted on the frame 11 along the up and down directions. A hydraulic mechanism for driving the upper die frame 12 to move is provided on the frame 11. When the sheet material 5 needs to be bent, the worker first places the portion of the sheet material 5 that needs to be bent on the lower die frame 13, and then starts the hydraulic mechanism to move the upper die frame 12 downward, thereby bending the sheet material 5.

[0042] like Figure 1 , Figure 3 , Figure 8As shown in the figure, the storage mechanism 3 includes a base 31, a lifting platform 32, two limiting plates 33, a slider 34, a first driving source 35, a third driving member, and two fourth driving members. The base 31 is located on the right side of the support frame 2 and is placed on the ground. The lifting platform 32 is slidably mounted on the base 31 in the up and down direction. A first driving source 35 is installed between the lifting platform 32 and the base 31. The first driving source 35 includes a first motor (not shown in the figure) fixedly installed on the base 31 and a first lead screw 351 installed at the output end of the first motor. The first lead screw 351 is arranged in the up and down direction. A first sleeve extending downward is installed on the lower end surface of the lifting platform 32. The first sleeve is sleeved on the first lead screw 351, and the first sleeve is in threaded cooperation with the first lead screw 351. A second sleeve 353 extending upward is installed on the upper end surface of the base 31. The second sleeve 353 is sleeved on the first sleeve. A convex block extending in the up and down direction is installed on the outer peripheral wall of the first sleeve. A first chute 354 adapted to the convex block is opened in the inner peripheral wall of the second sleeve 353 in the up and down direction. The convex block is slidably mounted in the first chute 354 in the up and down direction. Thus, when the first lead screw 351 rotates, the first sleeve rises or falls. A second chute is opened on the upper end surface of the base 31. The second chute is located on the right side of the first sleeve. The slider 34 is slidably mounted in the second chute in the left and right direction. The third driving member is used to drive the slider 34 to move. A first track groove 311 extending in the front and back direction is opened on the upper end surface of the base 31 on the left side of the first sleeve. A second track groove 312 extending in the front and back direction is opened on the upper end surface of the slider 34. The two limiting plates 33 are respectively slidably mounted in the first track groove 311 and the second track groove 312 in the front and back direction. The two fourth driving members are respectively arranged in the first track groove 311 and the second track groove 312. The fourth driving member is used to move the limiting plate 33 in the front and back direction, and the two limiting plates 33 are gradually inclined to the left from bottom to top.

[0043] The sheet material 5 is horizontally placed on the lifting platform 32. Multiple sheet materials 5 are stacked on the lifting platform 32 in the up and down direction, and the left and right ends of the sheet material 5 are respectively abutted against the limiting plates 33 on the left and right sides of the sheet material 5. Since both limiting plates 33 are inclined to the left, the left end of the upper sheet material 5 exceeds the left end of the sheet material 5 below it. When the processing of the sheet material 5 on the support frame 2 is completed, the first motor will start and drive the first lead screw 351 to rotate. The rotation of the first lead screw 351 drives the lifting platform 32 to move upward through the first sleeve, and then drives the lifting platform 32 to move upward by the height of one sheet material 5 through the first sleeve. In practical applications, it may be necessary to process sheet materials 5 of different sizes. To meet this requirement, the third driving member can control the movement of the slider 34. The movement of the slider 34 will adjust the distance between the two limiting plates 33 to adapt to sheet materials 5 of different sizes. This flexible design enables the equipment to process materials of various specifications, greatly improving the applicable range of the equipment and the flexibility of processing. The fourth driving member can adjust the position of the limiting plate 33 in the front and back directions. Through this adjustment, both the leftmost and rightmost ends of the sheet material 5 can be tightly abutted against the limiting plates 33, thereby ensuring the stability and accuracy during the processing process.

[0044] As Figure 8 , Figure 12 and Figure 13 shown, the third driving member includes a third lead screw 36 and a third turning handle. The third lead screw 36 is arranged in the second chute in the left and right direction. The third turning handle is fixedly installed on the right end face of the third lead screw 36. The slider 34 is sleeved on the third lead screw 36, and the slider 34 is in threaded cooperation with the third lead screw 36. When it is necessary to adjust the distance between the two limiting plates 33, the worker manually rotates the third turning handle, thereby driving the slider 34 to move in the left and right direction through the third lead screw 36, and then adjusting the distance between the two limiting plates 33.

[0045] As Figure 3 , Figure 8 shown, the fourth driving member includes a fourth lead screw 37 and a fourth turning handle. The two fourth lead screws 37 are respectively rotatably installed on the base 31 and the slider 34 in the front and back direction. The fourth turning handle is installed on the front end face of the fourth lead screw 37. When the size of the sheet material 5 to be processed changes, the worker manually rotates the fourth turning handle, thereby driving the limiting plate 33 to move in the front and back direction through the fourth lead screw 37, and then adjusting the position of the limiting plate 33, so that both the leftmost and rightmost ends of the sheet material 5 can be abutted against the limiting plates 33 on the left and right sides of the sheet material 5.

[0046] As Figure 8As shown, on the left and right end faces of the lifting platform 32, a first comb plate 321 and a second comb plate 322 are slidably installed in the left-right direction respectively. The left and right ends of the lifting platform 32 are in a comb shape. The combs on the first comb plate 321 and the second comb plate 322 are interlaced with the combs on the lifting platform 32. And slide bars 323 are installed on the front and rear end faces of the combs on the first comb plate 321 and the second comb plate 322. Slide grooves three 324 adapted to the slide bars 323 are provided on the front and rear end faces of the combs on the lifting platform 32. The slide bars 323 are slidably installed in the slide grooves three 324 in the left-right direction. An elastic member two 325 for moving the first comb plate 321 to the left to abut against the limiting plate 33 is provided between the first comb plate 321 and the lifting platform 32. The elastic member two 325 is a first compression spring (not shown in the figure). An elastic member three 326 for moving the second comb plate 322 to the right to abut against the limiting plate 33 is provided between the second comb plate 322 and the lifting platform 32. The elastic member three 326 is a second compression spring (not shown in the figure).

[0047] As Figure 1 , Figure 2 shown, the support frame 2 includes a first side plate 21, a second side plate 22 and a second driving member. The first side plate 21 is fixedly installed on the bending machine body 1. The second side plate 22 is slidably installed on the first side plate 21 in the front-rear direction. Two telescopic rods are installed between the second side plate 22 and the first side plate 21. The two ends of the telescopic rods are fixedly connected to the first side plate 21 and the second side plate 22 respectively. The telescopic rods are used to support the second side plate 22. The second driving member is used to drive the second side plate 22 to move in the front-rear direction. A plurality of rotating rods 24 abutting against the sheet material 5 are arranged in an array in the left-right direction on the upper end faces of the first side plate 21 and the second side plate 22. The plurality of rotating rods 24 are respectively rotatably installed on the first side plate 21 and the second side plate 22. And the rotation axes of the rotating rods 24 are arranged in the front-rear direction. The top ends of the rotating rods 24 extend beyond the upper end faces of the first side plate 21 and the second side plate 22. And the top ends of the rotating rods 24 are flush with the top end of the lower die holder 13. The rotating rods 24 are used to convert the sliding friction when the sheet material 5 slides on the first side plate 21 and the second side plate 22 into rolling friction, so as to reduce the resistance for the worker to move the sheet material 5 on the first side plate 21 and the second side plate 22. At the same time, it can reduce the damage caused by friction between the sheet material 5 and the first side plate 21 and the second side plate 22.

[0048] As Figure 1 , Figure 2 , Figure 5As shown in the figure, the second driving member includes a second lead screw 23, a third sleeve 25 and a second rotating handle. The third sleeve 25 extends forward and is disposed on the front end face of the first side plate 21, and is fixedly connected to the front end face of the first side plate 21. An installation hole penetrating through in the front and rear directions is formed in the second side plate 22. The second lead screw 23 is rotatably installed in the installation hole. The front end of the second lead screw 23 extends beyond the front end face of the second side plate 22, and the second lead screw 23 is disposed through the third sleeve 25. The second lead screw 23 and the third sleeve 25 are in threaded cooperation. The second rotating handle is fixedly installed on the front end face of the second lead screw 23.

[0049] When bending sheets 5 of different sizes is required, the worker manually operates the second rotating handle on the device. In this way, the worker can utilize the cooperation between the second lead screw 23 and the third sleeve 25 to accurately adjust the distance between the first side plate 21 and the second side plate 22. This adjustment is to accommodate various sheets 5 of different sizes to ensure that they can be properly placed on the device. Once the distance between the first side plate 21 and the second side plate 22 is appropriately adjusted, these two side plates can provide the necessary support for sheets 5 of different sizes. Such a design enables the device to flexibly handle materials of multiple sizes, thereby improving the versatility of the device.

[0050] As Figures 1 - 13 As shown in the figure, the loading mechanism 4 includes two material pushing plates 41, two material pulling rods 42, a second driving source and two first driving members 44. The two material pushing plates 41 are respectively rotatably installed on the front end face of the first side plate 21 and the rear end face of the second side plate 22. The rotation axes of the two material pushing plates 41 both extend in the front and rear directions, and the rotation axes of the two material pushing plates 41 are coaxially arranged. One end of the material pushing plate 41 far from its rotation axis is an abutting end 411. In the initial state, the abutting end 411 of the material pushing plate 41 is located on the right side of one end of its rotation axis, and the abutting end 411 is located at the lower left of the uppermost sheet 5. Track grooves three 26 and track grooves four are respectively formed on the front end face of the first side plate 21 and the rear end face of the second side plate 22. The two material pulling rods 42 are respectively slidably installed in the track grooves three 26 and track grooves four in the left and right directions, and the two material pulling rods 42 are located between the two material pushing plates 41. A roller 45 is rotatably installed at the right end of the material pulling rod 42. A one-way bearing (not shown in the figure) is disposed between the roller 45 and the material pulling rod 42. A first telescopic rod arranged in the front and rear directions is installed between the two material pulling rods 42. The front and rear ends of the first telescopic rod are respectively fixedly connected to the two material pulling rods 42. The first telescopic rod is used to keep the two material pulling rods 42 moving synchronously. The second driving source is used to drive the material pulling rods 42 to move in the left and right directions. The two first driving members 44 are respectively used to rotate the two material pushing plates 41.

[0051] The lower end surface of the uppermost sheet material 5 on the lifting platform 32 is at the same horizontal plane as the upper end surface of the limiting plate 33 on the right side of the sheet material 5. At the top of the limiting plate 33 on the right side of the sheet material 5 on the lifting platform 32, there is an upward-extending retaining platform 38. The left end face of the retaining platform 38 is a vertical plane. When it is necessary to move the sheet material 5 from the lifting platform 32 to the rotating rod 24, the driving member one 44 drives the material pushing plate 41 to rotate, so that the abutting end 411 of the material pushing plate 41 first moves towards the sheet material 5. After the abutting end 411 of the material pushing plate 41 abuts against the lower left end of the uppermost sheet material 5 on the lifting platform 32, as the material pushing plate 41 continues to rotate, the abutting end 411 of the material pushing plate 41 pushes up the left end of the uppermost sheet material 5, causing the left end of the sheet material 5 to deflect upward. At the same time, the right end of the sheet material 5 abuts against the retaining platform 38. After the sheet material 5 deflects, the driving source two drives the material pulling rod 42 to move to the right and enter the lower side of the sheet material 5. After the roller 45 on the material pulling rod 42 abuts against the lower end surface of the sheet material 5, as the material pulling rod 42 continues to move to the right, the inner ring and the outer ring of the one-way bearing on the roller 45 rotate relative to each other, and the roller 45 starts to roll to the right along the lower end surface of the sheet material 5. When the right end of the roller 45 moves to the right end of the sheet material 5, the left end of the sheet material 5 deflects downward under the action of gravity and rests on the material pulling rod 42. Then the material pulling rod 42 drives the sheet material 5 to move to the left, thereby driving the sheet material 5 to the upper end of the rotating rod 24 to the left. After the material pulling rod 42 resets, the lifting platform 32 rises by the height of one sheet material 5.

[0052] As Figures 2 - 5 shown, the driving source two includes a motor two (not shown in the figure) and a lead screw five 43. The motor two is installed on the side plate one 21. The lead screw five 43 is rotatably installed in the track three in the left-right direction. The output end of the motor two is connected to the lead screw five 43. The material pulling rod 42 on the side plate one 21 is sleeved on the lead screw five 43, and there is a threaded fit between the material pulling rod 42 on the side plate one 21 and the lead screw five 43.

[0053] As Figures 3 - 13As shown in the figure, the first driving member 44 includes a gear 441 and a rack 442. The gear 441 is fixedly installed on the blank feeding plate 41, and the rack 442 is installed on the blank pulling rod 42. The gear 441 and the rack 442 are meshed with each other. An elastic member 46 is installed on the blank feeding plate 41. The elastic member 46 is a torsion spring (not shown in the figure). The two ends of the torsion spring on the blank feeding plate 41 on the first side plate 21 are fixedly connected to the blank feeding plate 41 and the first side plate 21 respectively. The two ends of the torsion spring on the blank feeding plate 41 on the second side plate 22 are fixedly connected to the blank feeding plate 41 and the second side plate 22 respectively. The torsion spring is used to make the abutting end 411 of the blank feeding plate 41 located at the lower left of the uppermost layer of sheet materials 5. When feeding is required, the blank pulling rod 42 first moves to the right, and then the rack 442 moves to the right and meshes with the gear 441. As the blank pulling rod 42 continues to move to the right, the rack 442 moves to the right and drives the gear 441 to rotate, and then drives the blank feeding plate 41 to rotate. When the blank feeding plate 41 rotates, the abutting end 411 of the blank feeding plate 41 first abuts against the lower left end of the uppermost layer of sheet material 5 on the lifting platform 32. As the blank pulling rod 42 continues to move to the right, the blank feeding plate 41 drives the left end of the sheet material 5 to deflect upward. When the roller 45 enters the lower side of the sheet material 5, the rack 442 moves to the right side of the gear 441 and disengages from the gear 441. At this time, the gear 441 reversely resets under the action of the torsion spring and drives the blank feeding plate 41 to reset. When the blank pulling rod 42 moves to the left and resets, when the rack 442 meshes with the gear 441 again, it will drive the gear 441 to reverse. When the rack 442 disengages from the gear 441, the gear 441 rotates forward and resets under the action of the torsion spring.

[0054] The specific working principle of the present invention: After the workers complete the bending process of a sheet metal 5, they first place the bent workpiece on the conveyor. Subsequently, the second motor starts, driving the lead screw five 43 to rotate forward. The forward rotation of the lead screw five 43 causes the material pulling rod 42 to move to the right. At the same time, the rack 442 also moves to the right and drives the gear 441 to rotate. The rotation of the gear 441 further drives the rotation of the material deflecting plate 41. When the abutting end 411 of the material deflecting plate 41 contacts the lower left end of the uppermost sheet metal 5 on the lifting platform 32, the material deflecting plate 41 continues to rotate, and the abutting end 411 of the material deflecting plate 41 starts to lift the left end of the uppermost sheet metal 5 upward. When the left end of the sheet metal 5 is lifted above the roller 45, the material pulling rod 42 continues to move to the right, and the roller 45 enters the lower side of the lifted sheet metal 5. As the material pulling rod 42 continues to move to the right, after the roller 45 contacts the lower end surface of the lifted sheet metal 5, the roller 45 rolls to the right along the lower end surface of the sheet metal 5. When the roller 45 rolls to the right end of the sheet metal 5, the left end of the sheet metal 5 deflects downward due to gravity and finally lands on the upper surface of the material pulling rod 42. At this time, the second motor reverses, driving the material pulling rod 42 to move to the left for a reset operation. At the same time, during the process of the material pulling rod 42 moving to the left, it drives the sheet metal 5 above it to move to the left above the rotating rod 24. Then, the workers can continue to perform the bending work on the unbent sheet metal 5. At the same time, the first motor starts, and the lifting platform 32 moves up by the height of a sheet metal 5 to prepare for the next bending process.
